Sam 0ca61242b8 FEATURE: polyfill intersection observer for IE11 / iOS Safari ... This feature is used for defer loading of images and in future for post cloaking This gives us a polyfill so we can safely use the feature in problem browsers The polyfill supports "polling" but it does not appear we need it yet. If we discover anything odd here, consider setting poll interval per: https://github.com/w3c/IntersectionObserver/tree/master/polyfill ``` var io = new IntersectionObserver(callback); io.POLL_INTERVAL = 100; // Time in milliseconds. ``` Keeping the mutation observer cause we often mutate the DOM		2018-12-12 15:36:08 +11:00
